More specifically, I am inserting a picutre into a Visio Page. I would
like to save it as a stencil, which I can do, but the stencil file is
empty. It doesn't recognize the image as being a stencil master.
If the picture is not in the stencil document of your drawing you can save
the drawing as VSS but the shape in it will not be considered as a master.
So you have to drop programmatically the picture in the stencil document of
your drawing
